Prism Documents and Reports
PRISM Science Retreat
PRISM Seminar Series, Fall 2002
Puget Sound Dynamics
Goals of MIXED
1) Learn about the biophysical coupling of south Sound. Study the spring
bloom in a region vulnerable to nutrification
2) Integrate PRISM's numerical physical models of Puget Sound
3) Involve students in hands-on research
An overview of the project can be downloaded here,
and a talk Kate Edwards gave about MIXED is here.
MIXED will take place in Carr Inlet, the home of the ORCA profiler which
provides a multi-year water and meteorological dataset which will complement
the observations of MIXED. (Learn more about ORCA by viewing a talk
by Al Devol).
We invite the involvement of students in MIXED.

Puget Sound water circulation is modeled by Mitsuhiro Kawase using the
Princeton Ocean Model, (POM).
animation shows density and velocity at two different depths (4 and
31 m beneath the water's surface).
View Mitsuhiro's talk
about the modeling effort.
Later runs will be coupled to Cliff Mass' MM5 atmospheric model and the
Hydromet river runoff model and compared to MIXED observations.
Using the velocity fields from POM, the AquaticBiogeochemistry Coupling
model (ABC) will be used to study water chemistry and biological processes
for the MIXED time period.
Biofloat - Eric D'Asaro will release an instrumented float to track
productivity of a water parcel, as well as the conditions experienced by
the water parcel.
Profiles - Jan Newton will take profiles following the neutrally
buoyant float. Measurements include oxygen, nutrients, and chlorophyll.
ORCA - The MIXED results will be compared to ORCA observations.
Precipitation - Jeff Nystuen will deploy an acoustic precipitation
Currents - Two current meteres will be deployed.
Fieldwork/modeling participants include:
Newton - WA Dept. of Ecology
Kate Edwards, Jeff
Nystuen - UW Applied Physics Lab
Devol, Steve Emerson
- UW School of Oceanography
Support for components of MIXED comes from:
University of Washington Royalty Research Fund
Washington Department of Ecology
ORCA - EPA, NOAA, PRISM, and NASA
